Machines, of which the following descrip' tion, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This Ainvention relates to machines for completing the shoe lasting operation by forcing over the last bottom and'securingv the upper materials between the front heel seat tack and the end of the inseam at each side of the shoe. There is a space left by the sewing machine between the heel seat tacks and the beginning and the ending of the seam because, the sewing machine is unable to sew close to the tacks without loosening the tacks. An earlier machine for doing the work designed to be performed by the machine of this invention is shown and described in British specification No. 22,889/08. f l

f The object .of the present invention is to improve said prior machine in certain respects which the practical use of that machine has suggested.

One important feature of this invention `consists in mounting the upper tightening `device to stand normally in a. shoe receiving position substantially below the tacker. This arrangement facilitates the presentation of the shoe to said vdevice and the proper engagement of the shoe with said v device *to secure the desired upper tightendevice, which is pivotally connected to its' support for movement from and toward shoe receiving position, is held down yieldingly by a spring the force of which must i 1Siieciicatioii of Letters Patent.

I be overcome in lifting the shoe and thedevice into 'operative relation to the tacker. The purpose of this is toinsure a substantial downward pressure vof the device upon the slice bottom in order that it shall hold the shoe stock hard down upon the last bottom at the time a tack `is driven. It is found in practice that by the use of this arranger nient an operator can press the shoeV against the engaging device to tighten the upper vover the edge of the last and will then, by lifting the shoe to the tacker, press or lay the tightened lupper firmlydown upon the insole in position for it to be so secured that the upper will not be crowded outwardly again when the shoe is subjected to the heavy pressure of the heel attaching machine. y

Another feature of the invention consists in the association with the upper tightening blade employed in the earlier construction of means for vengaging the shoe on the side and forcing the upper and the heel stiifener firmly against the side facev of the last while the upper is being tightened. As is well known, the h eel stiffener and the stiff upper materials tend to bulge away from the said face of the last when they are bent over the serves to force said materials hard against the side of the lash and hold them there while the upper is being fastened, thus giving to the side of this portion of the shoe a better conformation to the shape of the last and a trimmer appearance.

Still a further feature of this invention 4consists in connections between the upper tightening device and the machine by which said device can be moved: into an inoperative, out-of-the-way, position to permit the use of the tackiiig apparatus for other work as, for example, for tacking innersoles to The object of this provision is to enable a single machine 'to be used for performing a plurality of operations in the making of a shoe which heretofore have requiredl separate machines. In carrying out this feature of the invention the 'upper' tightening device is arrange for normal movement about its pivotal support thrpugh an angle which is limited by a latch that can .be withdrawn to permit the upper tightening device to swing down away from the tacker into a position in which a clear space exists around the tacker for such presentation of the shoe as is required in tacking on the insole or similar operations.

' The several features of the invention will i appear more fully from the following depulley 2, which has on its front or ri hthand surface, as observed in Fig. 31, 'a riction face for engagement with the adjacent face of the camA block 4 that is fixed upon the shaft and through which the shaft is driven. The pulley 1s actuated. toward the cam block, to cause the shaft to be driven, by aspring 6 which connectsthe upper end of the lever 8 with the frame. forked to embra ce the driving shaft and is fulcrumed at its lower end at 9 to the frame.

The lever 8 is provided at 10 with a steel plate presentin a shoulder for engagement with a similar shoulder on a late carried by the horizontal lever 12, which is fulcrumed to a. swinging bar 14. Thisbar, which is pivoted to the frame at 15, has a roll that engages with a groove in the cam block 4. YThe horizontal lever 12 extends forwardly over an abutment 16, shown as -mounted for a slight pivotal movement,

which is carried by the stem 18 of the vertically movable nozzle 20 of the tacker.

The driving shaft is operatively connected through any suitable devices with means to deliver tacks to the inclined raceway 21, by which they are led to the nozzle 20. driver carried by the bar 22 is lifted b'y the cam 23 and actuated downwardly by the spring 24.

Between' the machine from and the post which carries it is an ,intermediate plate 25 having a forked forwardly extending end in which a carrier 30 is supported by a pivot pin 26. The carrier is in the form of an angle lever having a depending arm provided with an adjustable stop screw 2 8 to limit the movement ofthe carrier about the pivot. The forwardly extending arm of the carrier supports a bar 32 upon the front end of which is mounted by an upright pivot the upper tightening device 35, said device having -a thin blade-shaped end to enter the The leverl is The Upon the upper face of the bar 32 a plate 36 is held in vlendwise adjusted position by a binding screw '38. The front end face of this plate is arranged to engage the outer f edge and face of the welt whereby the welt isv positioned accurately with reference to the side face of the shoe. A plate 40 is pivotally connected to the plate 36 and adjustably held by a screw 42 spaced above said plate 36 to overlie and engage the upper face of the welt to prevent the welt from buckling when it is pressedfin'wardly. A spring encircles the stem of the yscrewV which connects the plates 36 and 40 holds the plate 40 in its uplifted position. The spring 45 is attached to thev intermediate plate -25 and presses downwardly upon the carrier 30 in front of its pivot 26 and requires a substantial force to be applied to the upper tightening device position shown in dotted lines in Fig. 1 in which the driver nozzle 20 is lifted for tri ping the tacker wiper. A latch 46 is firm y supported by a pivot in the intermediate plate 25 and has an arm curved around the pivot pin 26 and extending under the lower side face of the carrier 30, said latch providing suiiicient vertical playto permit the normal movements of the carrier about its pivot indicated by the full and dotted lines 1n Fig. 1. position lby a spring 47 but can be turned to withdraw it from the carrier 30 and permit the carrier then to swing down into a vertical position where unobstructed space around the nozzle 20 will be provided foi` manipulating the shoe in tacking on insoles or other tac ing operations. The latch 46 has a. tail piece 48 which is the member with which the stop screw 28 contacts. When the latch is `pressed backwardly this tail piece-is withdrawn from above the stop screw. The stop screw provides for varying the shoe re- The latch is held in its operative ceiving posltion of the upper tightening de- V- l' vice.

The use of the machine and the purpose of the improvements comprised in this invent-ion having been sufficiently explained in the `heelrseat` tacks, means constructedand arranged to engage the shoe stock'betwe'en the upperv and the welt end and tightening the low the edge of the shoe bottom to force the upper and heel stitt'ener against the side of the last in said upper tightening operation, and means tor securing the upper.
